Definitions

  • foam development associated with the presence or use of surface-active substances is a serious problem for a large number of technical processes.
  • foaming occurs when the paint is rubbed in by stirring in air . Due to this foam formation, the production of paints and varnishes is more lengthy, since the systems can only be filled and operated with a fraction of the available volume.
  • foam development can also occur if the user wants to apply lacquers or paints to the substrates. This can result in air bubbles which not only represent optical surface defects but are also weak points in the dried film, since the bubbles can easily burst due to impact.
  • Foams can also be formed in paper production due to the air content entered in the water cycle, which lead to faults. For example, foam spots can appear on the paper if foam gets on the paper web during sheet formation. As a result of the increasingly faster running machines, the risk of air being mixed into the fiber suspension increases, which can lead to a disruption of the dewatering process of the paper stock on the paper machine and ultimately to porous structures of the paper sheet. These disadvantages, which are known in principle, are exacerbated by the new paper machines with the more closed water circuits, since foam-forming and foam-stabilizing substances accumulate in the closed systems.
  • defoamers are sought to solve foam problems which are effective, do not cause surface defects, do not cause undesirable water sensitivity of the surfaces and e.g. in plasterboard do not interfere with the adhesion.
  • aqueous fatty alcohol dispersions which, as nonionic surface-active compounds, contain reaction products of ethylene oxide with 1,2-alkanediols with 6 to 18 carbon atoms can meet the requirements.
  • the 1,2-alkanediols are converted into the compounds of the general formula (I) by ethoxylation.
  • the ethoxylation can be carried out by processes known from the prior art, which, depending on the choice of alkoxylation catalysts, lead to products with narrow or broad homolog distribution.
  • the choice of the alkoxylation catalyst influences the range of addition products, the so-called homolog distribution, of the ethylene oxide onto the 1,2-alkanediols.
  • the catalytically active alkali metal alcoholates such as sodium methylate
  • addition products with a broad homolog distribution are obtained, while for example in the presence of hydrotalcite as the catalyst, the homolog distribution is very narrow.
  • the even-numbered fatty alcohols can, as is customary in fat chemistry, also be used in the form of technical cuts, such as those obtained, for example, after saturation of the unsaturated components from erucic acid-rich beet oil, peanut oil, castor oil, beef tallow or fish oil by hydrogenation.
  • saturated, straight-chain synthetic fatty alcohols having 16 to 28 carbon atoms are also suitable for the purposes of the invention, which can be obtained by the Ziegler process by oxidation of aluminum alkyls and subsequent hydrolysis. In this way, mixtures of even-numbered, straight-chain fatty alcohols (alfoles) are obtained.
  • synthetic fatty alcohols which are produced by oxosynthesis by the reaction of olefin with carbon monoxide / water. coff, such as odd alcohols, are suitable for the purposes of the invention.
  • aqueous fatty alcohol dispersions contain the fatty alcohols in amounts of 5 to 40% by weight, preferably 15 to 35% by weight, based on aqueous fatty alcohol dispersions.
  • aqueous fatty alcohol dispersions according to the invention can additionally 0.5 to 10 wt .-%, instead of the corresponding amounts of fatty alcohol, natural and / or synthetic waxes, aliphatic and / or contain alkali metal or amine soaps from aliphatic Ci _28 Fe acids.
  • natural waxes are both those which are obtainable in the processing of petroleum, bitumen and / or fossils, for example the paraffin waxes and montan waxes, and also the natural esters, ketones or a ide of natural Ci6-C32 fatty acids or of natural Ci6-C32 fatty alcohols such as stearyl stearate, stearyl behenate, behenyl behenate, stearone, glycerol tristearate, glycerol tribehenate, pentaerythritol tetrastearate, hydrogenated castor oil, ethylene bisstearamide, erucic acid id, carnauba wax and natural waxes, beeswax, etc.
  • fatty acid component, fatty acid soap component and / or waxes are added in an appropriate proportion to replace the fatty alcohol, the minimum amount of fatty alcohol present in the composition is at least 5% by weight, preferably at least 10% by weight.
  • the aqueous fatty alcohol dispersions according to the invention also contain anionic surface-active compounds selected from the group consisting of alcohol sulfates, ethoxylated alcohol sulfates, fatty alcohol ether sulfosuccinates and fatty alcohol ether phosphates.
  • anionic surface-active compounds are Cs- ⁇ -fatty alcohol ether sulfates with 6 to 100 mol of ethylene oxide, preferably with 20 to 60 mol of ethylene oxide. Suitable examples of this are sodium lauryl ether sulfate ethoxylated with 30 mol ethylene oxide and sodium lauryl ether sulfate ethoxylated with 50 mol ethylene oxide.
  • aqueous fatty alcohol dispersions according to the invention contain the non-ionic surface-active compounds in amounts of 0.5 to 5% by weight. and the anionic surfactant compounds also in amounts of 0.5 to 5% by weight.
  • aqueous fatty alcohol dispersions which, in quantities of 5 to 40% by weight, preferably 15 to 35% by weight, of fatty alcohols, optionally in a mixture with natural and / or synthetic waxes, aliphatic Ci4-C28 fatty acids and / or alkali metal or amine soaps of aliphatic Ci4-C28-r " fatty acids,

  • Common additives are protective colloids, other stabilizers or liquid fatty alcohols, fatty acids, fats, oils and silicone oils in order to improve the consistency of the dispersed phase without impairing the effect.
  • aqueous fatty alcohol dispersions according to the invention can be prepared in a manner known per se. It is thus possible to convert the fatty alcohol into a melt and to stir it into water, the dispersions or even isolated emulsions being formed by cooling the melt. However, the fatty alcohols can also be stirred into optionally heated water and the water brought to such temperatures until a melt is formed. Stabilization is then carried out by adding the above-mentioned surface-active compounds. Gel formation, as often occurs in the prior art, does not take place here.
  • the aqueous fatty alcohol dispersions according to the invention are suitable for many uses since they can be metered well and have storage rod 1 are. Even at higher levels of natural fatty alcohols, they show very good storage stability, which is maintained even at temperatures below 15 ° C. They are also able to suppress or regulate foam.
  • a further embodiment of the present invention therefore relates to the use of the aqueous fatty alcohol dispersions described above as anti-foaming agents, preferably in the paper industry, in the wastewater sector, in the construction industry and in the production of water-based paints.

  • the aqueous fatty alcohol dispersions according to the invention are suitable as an additive for dispersion-bound plasters, since they extend the processing time and thus improve it.
  • the tendency to crack the dispersion-bound plasters is significantly reduced, a reduction in water absorption and thus an increase in the hydrophobizing effect of the plasters are further advantages.
  • aqueous fatty alcohol dispersion composed of 30% by weight of a natural Ci to Ci8 fatty alcohol mixture with about 60 to 70% by weight stearyl alcohol, 0.25% by weight sodium lauryl ether sulfate was ethoxylated with 30 mol E0, 0.5% by weight .% C12 / 14 alkane epoxide ring-opened with ethylene glycol ethoxylated with 10 mol E0 and 69.25% by weight water.
